Complex Single Molecules Successfully Manipulated On Atomic Scale By Manual System

by on November 16, 2014
Scientists at the German Jülich Research Center (Forschungszentrum Jülich) have developed a powerful new method that allow real-time, interactive manual manipulation of individual molecules.  All previous attempts have worked on individual atoms, which is actually an easier problem.  In a demonstration, an operator manually carved out the word “JÜLICH” on a single layer of atoms, […]

Scattering In Single-Layer Material Reveals New Understanding Of High Temperature Superconductivity

by on November 13, 2014
Placing a 2D single-atom thick layer of iron selenide over a strontium-titanium-oxygen (also known as strontium-titanate, STO or SrTiO3) substrate massively increases the superconductivity temperature of the bulk 3D form of iron selenide from a chilling 8 Kelvin to a balmy 70 Kelvin (0 Kelvin is absolute zero, the lowest possible temperature).  High temperature superconductors […]

Hubble Finds 200 Billion Orphan Stars Adrift Between Galaxies, Torn Free Due To Collision

by on November 10, 2014
NASA’s Hubble Space Telescope, as part of its Frontier Fields project, has detected the glow of a massive collection of approximately 200 billion orphan stars ripped from their parent galaxies billions of years ago due to a major collision.  The distance to the clusters is 4 billion light years.  The cluster itself is nicknamed “Pandora’s […]

A Genetically-Engineered Modular AND Logic Gate Curtails, Kills And Prevents Metastasis Of Bladder Cancer

by on November 8, 2014
Scientists have designed a new kind of modular, “logic circuit” therapy, by realizing a genetic AND gate that combines information from two kinds of inputs to render an active therapy.   The circuit was applied to bladder cancer cells by uptake as a strand of DNA containing the genetic components.  When taken up by normal cells […]

Combustionless Electricity Generation From Jet-Fuel With Novel Biofuel Reactions

by on November 7, 2014
Scientists have created the first room-temperature fuel cell that exploits the high energy density of jet fuels to generate electricity directly without the need for an internal combustion engine.  Prior attempts to use alkane-based liquids such as jet fuel have led to degradation of the metal catalysts due to presence of high concentrations of sulfur […]

Synthetic Platelet Super-Mimics Halt Bleeding Three Times Faster

by on November 6, 2014
An additive nanoparticle manufacturing process has been used to design and realize a synthetic platelet for the first time.  The platelets are “super mimics”, matching the natural shape, size, flexibility, and surface biochemistry of real platelets unlike prior incarnations that match only one or two qualities.  The synthetic platelets were applied in an animal model of bleeding to […]

Drug Unlocks Malleable, Fast-Learning, Child-LIke State In Adult Brain

by on November 4, 2014
Professor Carla Shatz of Stanford University and her colleagues have discovered a way to revert an adult brain to the “plastic”, child-like state that is more able to form new connections quickly.  The technical term “plastic” implies the ability to adapt or shape itself to new conditions.  The striking results were revealed through experiments on […]

Highly Efficient Laser-Ablation Propulsion System At Supersonic Speeds

by on October 30, 2014
Conventional rockets and aircraft exploit a combination of conservation of momentum and Newton’s third law to generate thrust via the expulsion of propellant mass from a nozzle to escape Earth’s atmosphere or travel through the atmosphere or space.  However, the expense and difficulty of the technique has prompted engineers and scientists to devise alternative methods […]

World Losing 2,500 Hectares Of Irrigated Land Per Day To Salt Damage

by on October 29, 2014
A study by scientists at the UN University’s Institute for Water, located in Ontario, Canada, revealed that 17 million hectares of arable land has been lost to salinization in the period from 1995 to 2013.  The loss rate is computed at a staggering 2,500 hectares per day, or equivalently 4,600 American football fields.  Viewed another […]

Clinical Trial Shows Cocoa Diet Reverses Age-Related Memory And Cognitive Decline: 60 Year Old Cognition Reverted to 30-40 Year Old

by on October 27, 2014
A new study and clinical trial by scientists at Columbia University Medical Center has shown that in healthy human adults, a diet of cocoa that is rich in flavanols is able to reverse the effects of age-related memory decline.  Imaging reveals one region of the brain that is responsible for the improvement in cognition.  The […]
